This paper presents on the design of 2x2 Rectangular Microstrip Patch Array Antenna with frequency at 4 GHz using metamaterial technique for wireless application. Metamaterial technique used to enhance the characteristic of antenna. Defected Ground Structure (DGS) one of the techniques used to contribute the metamaterial features to the antenna. The construction of circle DGS at ground plane contributes the metamaterial features to the array antenna. Rectangular array antenna without DGS and rectangular array antenna with DGS has been simulated, fabricated and measured. The both antenna was designed and simulated using Computer Simulation Technology (CST) Microwave Studio and both antenna were fabricated on FR-4 substrate with dielectric constant of 4.7, thickness of 1.6mmand tangent loss 0.019 respectively for comparison antenna performance purposes.
